A couple of readers pointed out a significant omission from the survey, Morris R. Cohen. Feel free to list other omissions in the comments, but take a moment to say why they were significant and should be appreciated today. More generally, I'd be keen to hear from readers what they think of the philosophers on this list, why they are significant and still worth reading. That will surely be more interesting than the mere ordinaly listing.
